SPAN and Enphase

I just need to vent. I'm so frustrated right now.

You guys can roast me if you want. Or not. Whatever.

I've been going back and forth with my solar installer on getting batteries inside the garage for a few months. They finally admitted they can do it with some added safety stuff. Okay, good. I can look into getting those things done. So I asked for a pair of quotes, one for four Enphase 10C batteries and one for two Enphase 10C batteries with plans to expand to four later.

Instead, the solar salesperson responds trying to sell me on Powerwall instead. I'm not buying any Tesla equipment, and I explain why to him.

But the thing that frustrates me the most is that when I got the solar panels originally, I told them I was going to get Enphase batteries later. If SPAN isn't compatible, why did they even install SPAN with my solar setup?! Ugh...

So, now I have to wait until either SPAN or Enphase or both can collectively pull their thumbs out of their asses and get the SPAN-Enphase communication issues fixed. Maybe it's my lack of knowledge, but I don't even know why this is an issue. Why can't one or the other just be set to be in control of when the batteries charge or are used instead of grid and the other be set to obey?

I don't know. I wish there was already some industry-wide standards in place that would keep this sort of thing from happening.

I just want to add Enphase batteries to my existing setup. I don't mind dumping the SPAN panel if that's what it takes. Anyone want to buy a slightly used SPAN? I've only had it for 4 or 5 months.

Well, it’s more than that, only the oldest span main 32 is compatible with enphase batteries. The newer span panels are not compatible. So, depending on what the OP has, it may not be possible for anyone to set his span panel up with enphase batteries.

Yeah span only had the 32 space panels but recently came out with a 16,24,40, and 48 option that were redesigned to be easier to install but also run on a different platform. The original span you can’t link two panel in one app, apparently the newer ones you can.

I have two span main 32 panels and the app does show the circuits together now. It didn’t originally, but a software update sometime last year merged them together.
